Question

I am completely lost someone help!:)

Answer 1

`x = 26`

Explanation:

Given

The above triangles

Required

Find x

The two triangles are similar. So we make use of the following equivalent ratios, to solve for x

`XZ : ZY = JL : LK`

Replace each side with their measurements

`13 : 10 = x : 20`

Express as fraction

`(13)/(10) = (x)/(20)`

Solve for x

`x = (13)/(10) * 20`

`x = 1.3 * 20`

`x = 26`
